OSI Layers 1) Physical Layer: The physical layer is at the bottom of this model. It deals with crude data that is in the form of electrical signals. The data bits are sent as 0s and 1s. 0s correspond to low voltage signals and 1s correspond to high voltage signals. The mechanical aspects of communication‚ such as wires or connectors come under this layer. The physical layer also deals with how these wires‚ connectors‚ and voltage electrical signals work. Also‚ the process that is required for

for every being on the Earth. Why? What causes the Earth to degrade‚ to get sick? People are too irresponsible. They don’t care about the Earth. They burn things without a limit‚ throw trashes into the sea‚ and chop down trees as their will. They just don’t care about it! People are so inconsiderate. They don’t think about the consequences of their actions. Everything is about benefit‚ selfishness‚ and self pleasure. They think the matter won’t cause them anything and don‘t bother about it

1. Physical Layer. Is the physical connection between the sender and the receiver. It includes all the hardware devices (computers‚ modems‚ and hubs) and physical media (cables and satellites). This layer specifies the type of connection and the electrical signals‚ radio waves‚ or light pulses that pass through it. 2. Data Link Layer. Is responsible for moving a message from one computer to the next computer in the network path from the sender to the receiver. This layer has 3 functions: a
